Used Audi cars for sale near St. John, IN under $20,000

I just purchased a car from Castle Hyundai of Oak Lawn, and I couldn’t be more grateful for the experience. From start to finish, the team showed true professionalism, care, and integrity—qualities that can be hard to come by in the car-buying world. Now I truly understand what they mean when they say “Drive Happy!” Jim (Sales Manager), Nick (Sales Consultant), Brennan (Internet Representative), and John (Finance Manager) were an absolute pleasure to work with. They went above and beyond to make sure I felt informed, respected, and supported throughout the process. They were transparent, never pushy, and always willing to answer my (many!) questions with patience and honesty. It was clear that they genuinely cared—about the car, the deal, and most importantly, about me as a customer. They didn’t just meet expectations - they exceeded them. The entire process was smooth, respectful, and even enjoyable. These are good people who take pride in doing right by others. Thank you to everyone at Castle Hyundai of Oak Lawn—you didn’t just help me get a great car, you made the whole experience one to remember. You went the extra mile (pun absolutely intended) and because of you, I now Drive Happy!

I can tow 7700 pounds and haul 7 passengers. Sure the 3rd row seat is small, but so are kids, who would be riding back there anyway. Way better value than a Suburban- and does almost all the same things only better- if you need to tow something large, you have to consider this option. The interior finishings are truly German Luxury.

Just bought a car here today. Kimmy was very helpful and friendly, and overall had a great experience. Didn't feel pressured at all at any point in the process, there were no sales tricks or anything like that, and got a great car for a great price.

Very smooth comfortable ride. I have a Q5 2018 and so far no problem. Never thought I will get used to driving a SUV since my last car was an A6 which I kept for 13 years.

Traded in my Tahoe for this and have loved every minute driving this car! I have one in a car seat, and still have plenty of room. Such a smooth drive. I test drove so many cars and this by far beat them all. You get so much for the money, plus great safety ratings!

It's great the ride is very quiet and comfortable, smooth and it will get you a speeding ticket. Audi has a great warranty on their vehicles.

This car has so many features and rides awesome. It handles great and is very comfortable. I highly recommend this vehicle to anyone who is considering it.

I can’t tell you how much I love this car. Drives like a dream compared to my Cadillac Escalade. Handles well with plenty of acceleration. Nice clean designed exterior and well appointed interior. Only flaw are the drink holders and the lack of remote start since it is German.

I had a good experience buying my car from Chicago Cars US. Albert was my salesman, who greeted us with a friendly demeanor. Albert was knowledgeable regarding my car and answered all of our questions. Chicago Cars US staff from Albert, Jacob and Chris were friendly and very professional. I will and have recommended Chicago Cars US to family and friends.

I was very unsure about stepping out get a car that I will own without a co signer I’m very grateful I was able to do it by myself

We drove an hour to this location specifically for a recall service. We were not satisfied with a local dealerships service department. From the moment to pulling the car in the shop to the end of being complete, the service we received was very pleasant. The Service Advisor , Jim DeVault is very personable and professional & very happy to all address our concerns and request. The waiting room was a plus! The 1 and only thing I would suggest to be honest is keep the television on a neutral program. ( We agreed with a few other waiting customers , we'd rather watch a cartoon ;)) We will be back for any of cars needs. Thank you !!!!

I have owned myAudi A5 premium plus 2.0T for over 9 years,I am the second owner. I have looked at newer ones and the S5 and the RS5 but have kept firm with the A5. My car is monsoon Gray with saddle interior. I have 51000 miles on it and I get about 25 mpg. The comfortable, quiet ride is only surpassed by the 8 speed at in sport mode as it effortlessly and flawlessly brings me to 70mph on the pa turnpike. Wow, still makes me smile after 9 years and smiles per mile is the most important thing for me now. When I get out of her I still have to take a moment to admire her lines and design. I have owned many cars, from many very competent manufactures but the Audi A6 to me is that 1 girl I will keep forever.

Great experience salesman was awesome. Took only two hours from the time we got there till the time we were driving off the lot bought a really nice car for a low amount of money.

The car was a 2 year old used car, but was meticulously cared for and lightly driven. Interior was in exceptional condition and it featured the options and color combo I desired.

Jeff is a cool and understanding guy! Made it nice and easy! Very professional and knows his job…

My first audi ever. So far i have driven it for 9 months and honestly has been problem free. Great value mechanical wise. Inside styling is nothing special. Infotainment system is hyper dated; the only issue i really have is the bluetooth randomly deactivating. Over all I was expecting the q3 to be a head ache and finally its not. For a cross over hatchback suv there shockingly a lot of space which for me is the whole reason why it might be hard to part with it one day!

Bought a tesla from their lot in Indiana. Can't say anything bad about them. Was my first time purchasing a car remotely so i have put a lot of trust into them, and so far it's looking good. The car had a few minor issues typical for model X of that year, but I sort of expected that. Both people I spoke on the phone were really helpful, the shipping was delayed by a day but it was communicated properly, so everything went well.

2021 a5 PREM Plus; B&O 7th audi I've owned & they just keep getting better. Not a fan of the tap every time screen I want to do something feature which is fairly new. This one could be a keeper! The stereo is very high quality & handling rocks, quick & nimble. Sport suspension is a personal choice, always order it. Stiffer but smooth. Car is quite. Sport seats heated, heated mirrors, heated steering wheel. Need I say more?

Good customer service, very polite, nice vehicle. A very clean establishment. I would recommend this company. I hope nothing does not change my mind.

The car is a driving dream. Just two interior negatives for me: a very small trunk for even two medium suitcases and a cup holder design that sucks - under front dash so a tall glass/mug won’t fit. Even if it did, it’s blocking the. heating/air control. Please improve those by 2022 when I lease the next!

Chris and Matt are all world! Love my car and our entire experience buying from them. Very responsive and dependable. Knowledgeable as well. Joey

I love the lines of the car. It’s fun to drive, so smooth and quiet. It has a lot of great features. I love it!

We bought this car used without much planning. I didn't think I would like it as much as I do. Exterior styling is outstanding, decent power, great handling, with lots of amenities on the inside

Kimberly Smith is the best, I recommend buying your next vehicle here , love the service

The goods: Perfectly blends performance and comfort. Easily gets ~40 mpg during the summer time on highway drives without sacrificing any power (2.0T Premium Plus Quattro) . DSG is pretty fun when driven aggresively. Tech still feels fresh for a 2017. B&O sound is stellar. Very reliable despite the VW/Audi reputation in the past. This is the ultimate daily sleeper in my opinion. The not so good: DSG shifts quite harshly on low speed or during bitter cold months when the car is not warm enough. DSG maintenance is also quite costly and has to be done every 40k miles. Other nitpicky items: Audi non-sport seats have pretty short thigh support, so get the sport package with the thigh extenders, they are totally worth it. The need to use infotainment screen to put wiper in service position and check oil level (yup, no dipsticks) is unnecesary. Brake pad wear sensors are annoying when they go off. Major service reminder reset needs to be done at dealership, so it can be a little pricey. Overall, I think this is one of the best cars I've ever owned. I usually like to get the top trims, but Premium Plus (mid trim) is the way to go and has a lot more equipment than you'll need. The nickpicky items I think are common in modern cars, so not really a deal breaker.

Carly was the best salesperson I have ever had! The jeep is amazing, and I would send anyone her way.

This car entered to my standards and preferences. The car is ergonomic and stylish as well. In terms of performance, this car is legit and well rounded.

I bought my second truck in 4 years from Bose. The first was a champ. It did all I asked of it and remained reliable the entire time I owned it. I needed more weight and tow capacity and ended up back at Bose. Same great experience as the first time. The sales staff was helpful, open and directly answered my questions. I never experienced any evasion from them or doubt that they are being truthful. Their assistance with financing was great. It's been three months and after a few maintenance stops and a new set of tires, I'm very happy with this truck. Understand you're buying used and plan accordingly. If you want perfect, buy new. Although that's no guarantee either. Good, solid vehicles at a decent price. I absolutely will return to Bose should I be in the market for another vehicle. Incidentally, the first truck is still in the family being a reliable hauler. Can't beat that!

a great car in all respects. Fun to drive. Consumer Reports recommends the 2016 and 2018 models for reliability. I highly recommend it. well built

Although I'm quite biased to Audi for a multitude of reasons, the A5 is absolutely perfect. Jam packed with features. I'm extremely impressed with the virtual cockpit. Currently 3 years old any person could look at the exterior, open the door, sit down in the passenger seat and think this is a 2022. My personal favorite thing about Audi is how well they do with their legacy. Every car in their lineup ages so well.

Real curtious and knowledgeable staff I would tell my friends and family about this car lot

This is our first Audi and we fell in love with the brand. Audis just drive better than other cars. This is a great handling car, and very comfortable for how low it sits. The only down side is how much parts and labor cost on these cars. $500 to replace a headlight bulb. Interior quality is far above most cars and the styling is so beautiful. Bottom line is that it costs to be cool. We have had very few issues with our Audi and will probably own another someday.

Bought used and owned for over a year now and this car is amazing! smooth ride, great fuel economy, luxurious and very well crafted. I have been in an accident with this car and it held up very well and is a super sporty yet safe and practical car. 10/10 would recommend!!
